Answer by artiebits for Npm install cannot find module 'semver'

I had the same error. npm uninstall npm -g, rm -rf node_modules didn't help me, because when I tried I was getting Error: Cannot find module 'semver'. But I solve my problem with these steps (this will delete other global modules you may be using):

• sudo rm -rf /usr/local/lib/node_modules
• sudo rm -rf ~/.npm
• brew uninstall --force node
• brew install node

Hope this will help those who are getting a similar problem.
